west of Milecastle 79 where the route of Hadrian's Wall changes direction. Hadrian's Wall itself is visible at this location as an irregular bank up to 14 metres wide and up to 1 metre high at the bend. Turret 79B (Jeffrey Croft) () is situated about 250 metres southeast of the houses at the east end of Bowness-on-Solway in the field known as Jeffrey Croft. Its site is indicated by a very slight platform, visible on the ground. It was partially excavated in 1934. The excavations found the south and west walls of the turret. It was originally built as a free-standing stone tower abutting the Turf Wall. It is the most westerly turret known on Hadrian's Wall. References 79 Roman sites in Cumbria
